Good Afternoon
I'm having trouble with the sync speed of a new 877, to a newly installed BT ADSL line. I realize there are many threads regarding this issue, and have tried the various DSL firmwares suggested in the forums including 4.0.017 and 4.0.018. Have also tried with the various DSL operating modes. All pretty much sync at the same speed.
The line has been live for 3 days, BT will not assist at the moment as the line is still in the training period. However the line will not achieve a downstream speed higher than 600Kbps, the upstream speed also appears to be consistantly slightly higher. I notice the downstream attenuation isnt great, however i would of thought we would still be looking at 4-8Mbps connection.
Ive included the interface details below, and suggestions, things to try or advice appreciated.
Regards
Paul
